An argument over food turned fatal Wednesday evening when a 13-year-old boy shot and killed his 6-year-old brother before turning the handgun on himself, according to preliminary information from Pasco County Sheriff Chris Nocco.

Before killing himself, the 13-year-old also shot and wounded his 16-year-old brother, Nocco said. The 16-year-old called authorities at 6:19 p.m. and was rushed from his Hudson mobile home to a hospital with a gunshot wound that is not considered life threatening.

"This is a horrific scene," Nocco said. "This is a nightmare when you hear about the ages of these boys, a 6-year-old that was probably playing in his room, an argument over food and he lost his life."
